This PR adds the crate
hla, the DSL and high level assembler used to generate the block multiplier. The description of the block multiplier itself using this crate is in codegenMotivation
The primary purpose of the HLA is to simplify the interleaving of multiple implementations of an algorithm, enabling the combined version to utilize different execution units concurrently in a robust and reliable way. For example, an algorithm performing Montgomery multiplication and reduction can be implemented using both floating-point SIMD instructions and regular integer multiplication. Because these operations target different CPU pipelines, we can exploit instruction-level parallelism to achieve higher throughput.
